MATRIXDELIVERING MECHANlSIVl.

SPECIFICATION forming part of Letters Patent No. 392346, dated November 6, 1888.

(No model.)

T all whom. it may concern..-

Be it known that I, OTTMAR MERGEN' THALER, of the city of Baltimore and State of Maryland, have invented certain Improvements in Mechanism for Delivering Matrices, 850., from Magazine-Tubes, of which the following is a specification.

the discharging devices.

This invention relates to an improved mech anism for discharging matrices or types one at a time from the lower ends of-magazinetubes in which they are arranged one upon another, and is intended more particularly for use in machines of thetype represented in Letters Patent of the United States No. 317 ,828, dated May 12, 1883, and No. 347,629, dated August 17, 1886.

The particular aim of the present invention is to secure a positive delivery of the matrices from the tube to prevent the discharge of more than one at a time, and to prevent them from tipping or falling out of a vertical position until they are carried properly downward into the guide or carrier by which they are conveyed to the point of assemblage. As the magazine-tubes will be arranged in series and each provided with the feed mechanism-a duplicate of the others-J have deemed it sufficient to illustrate herein a single tube and its connections.

' In the accompanying drawings, Figure 1 represents a perspective view of a magazinetube provided with the improved feed mechanism, the parts being in their normal position. Fig. 2 is a similar view with the ejecting-slide depressed and in the act of delivering a matrix into the conductor below. Fig. 3 is an inside face view of the delivery-slide. Fig. 4 is a transverse vertical central section through the lower end of the tube and the delivery devices. Fig. 5 is a cross-section on the line y y of Figs. 1 and 4 on an enlarged scale. Fig. 6 is an elevation in outline showing the preferred connection of the finger-key with Figs. 7, 8, 9, and 10 are diagrams illustrating the action of the dis charging and detaining devices to effect the delivery of the matrices one at a time.

Referring to the drawings, A A represent the matrices with which the present device is designed to operate, each matrix consisting, like those in my previous patents above referred to, of a flat metal plate provided near the upper end with supporting-shoulders a a on opposite sides, and each adapted at its lower end to bear in a notch or recess in the top of the matrix next thereunder, so that when arranged in a column one above another they will descend freely through the magazinetube.

B represents the upright magazine-tube, which may be of any appropriate construction and of any sectional form adapted to receive the matrices in an upright position in a single row or column. At its lower end this tube is connected firmly to a metal plate or frame, 0, designed to support the various operative parts hereinafter described. This plate is provided with a groove or channel forming a continuation of the bore of the Inagazinetube, so that the matrices may descend therethrough. At its lower end this passage is left open on one side, but partially covered by a verticallysliding plate, D, carrying at its middle an elastic finger, E. The lower end of this finger tends to spring inward, and is provided with a lip or shoulder,E', beveled on its upper side, so that in rising with the slide it may ride over the matrices and engage over their upper ends in order to force them downward as the slide descends. At its lower end the plate is provided with two arms, I), the lower extremities of which are bent horizontallyv beneath the end of the tube or passage in order to receive and support thelower end of the bottom matrix, which will. rest thereon in the manner shown in Figs. 1 and 2.

To theslide D there is connected an operat ing-lever, F, pivoted to the support 0 and connected to one end of aspring, G, by which the lever and slide are lifted and held normally in the elevated position shownin Fig. 1.

The lever F, I propose to connect in any suitable manner with a finger-key,by which it may be conveniently operated to depress the slide. A simple arrangement is that represented in Fig. 6, in which I-I representsa rod extending downward from the rear end of the lever and connected to the rear end of a centrally-pivoted finger-key, I.

To the frame G, at one edge of the tube or channel,I pivot near its middle a detent-lever, J, having at opposite ends the two lips d and (2, which are projected alternately through openings into the tube for the purpose of arresting and supporting the matrices, as hereinafter explained. The upperend of this detent is provided with a pin, y, and the slide D, provided with an inclined shoulder, h, so arranged that as the slide completes its rising motion the incline,acting on the pi n, forces the t upper lip, d, of the detent into the tube, the

IO same action causing the lower lip, e, to be witlnlrawn. At its lower end the detent has an inclined surface, 1', designed to eneountera corresponding surface, j, on the lower end of the slide D, so that the slide,in eompleting its descent to deliver the matrix,causes the detent until it is carried to its place in the grooved gnideKorothcreonductor. This conduetorwill be provided with one or more wires stretched longitudinally in its bottom, so that they may yield laterally and spri ng overand into engagement with the lower shou ldcr, 1/,01' the matrices as the latter are forced down into the con- (luctor, the wires thus engaged serving to hold the matrices down and prevent them from being tipped out of their upright positions or blown out of the top of the conductor as they advance therethrough to the point of assemblage at its end.

The retaining-wires in the bottom of the conductor are not alone claimed as partof the present invention, but form the subject of a separate application filed by me on the 17th day of July, 1886, Serial No. 208,296. In this connection the present device is of special im- 2o normally in the positions shown in Figs. 1, l, and 7, the bottom matrix, No. 1, bearing upon and being sustained by the feet at the lower end of the slide,while the matrix nextabove,

soon as it islowercd to the proper point.

No. 2, is supported by the upper lip, (7, of the If new the finger-key be actuated and the slide carried downward, the linger E of the slide,

acting on top of the bottom matrix,will carry it positively downward until it reaches the 30 proper position in the conductor K or other receiving device, as shown in Fig. 2. This conductor will be combined with a blast-tube t or othcrsuitablemeans for conveying the matrix laterally off from the feet of the slide as As the slide descends, and before it delivers the bottom matrix, its incline j strikes the lower end ofthe detent J,throwing the latter into the position shownin Fig. 2, whereby the matrix No. 2 is released from the upper end of the detent and permitted to fall upon the outgoing I The secmatrix, No. l, as shown in Fig. 9. end matrix, resting on top of the other and sustained thereby, continues its descent until its shoulder encounters the lowcrlip of the do tent, as shown in Figs. 2 and 10, when its descent is stopped thereby. The advantage of releasing the second matrix before the first is discharged lies in the fact that the second 5 matrix is lowered. gradually for the greater part of its movement instead of: beingdropped the entire distance, so as to strike violently on the matrix below. After the delivery of ma trix No. .l. the slide 'rises to its original posi- 5 tion, and as it completes its upward move ment it again operates the detent, throwing its upper lip inward, so that it will sustain matrix No. 3, and at the same time withdrawing its lower lip, so that matrix No. 2, which is now at the foot of the column, is released and permitted to rest on the feet of the slide, so that it maybe in turn discharged by the next descent of the latter.

.It is to be remarked that by the above com- 55 bination I am enabled to carry the bottom matrix out of the magazine in a positive manner and to continue its downward movement vantageous, in that itprotects the descending matrices from the force of the blast, so that they may be certain to reach their proper places. It is manifest that the form and arrangement of the parts herein shown may be variously modified without departing from the limits of myinvention. For example, the slide may be connected to the remaining portions in any suitable manner, and the form of the detent and of the devices by which it is vibrated may be modified, provided only they are adapted to receive the movements herein described. As shown in the drawings, the slide is guided or held on one side by a lip, m, seated in a vertical groove in the edge of the plate 0. At the opposite side it is held by its up right arm, seated in grooves in the frame 0, and held in place by set-screws n, engaging over its edge.

lcommonly provide the magazine-tube at its top with a suspending-hook, o, by whiehit maybe suspended from the top of the machine, and I attach the spring G at its upper end to an arm, I, fixed to the tube. This arrangement admits of the magazine-tube and the discharging devices being instantly unhooked and removed from the machine without disturbing or disconnecting any of the connecting parts.

Having thus described my invention, what I claim is- 11. In combination with a magazine-tube, a vertical delivery-slide provided with a lateral foot or flange at the lower end to sustain the outgoing matrix.

2. In combination with a magazine-tube, a. vertical delivery-slide provided with a foot to sustain the outgoing matrix and with the yielding lip to engage said matrix and effect its positive delivery.

3. In. combination with a magazine-tube and a vertical carrier to deliver the matrices therefrom, the vibratory detcnt arranged to engage the matrix at its two ends alternately.

4. The magazine-tube, in combination with the reciprocating carrier providedwith matrixsustaining feet and the ejectingdip, and the centrally-pivoted dctent to hold the matrices in check.

5. The magazine-tube and the slide movable longitudinally thereof, in combination with.

the lever having a middle fulcrum and connected at one end to the slide, the spring acting to raise the slide, the finger-key, and the rod between the finger-key and lever.

8. In combination with the magazine-tube and the channeled plate attached to its lower end, the ej ecting-slide having one edge guided by a lip seated in a groove in said plate and its opposite edge seated in a second groove and confined therein by screws or other fastenings, substantially as described.

9. In combination with a magazine-tube, a reciprocating carrier or ejector provided with a lip to effect the discharge of the matrices, and the matrix-detaining mechanism having two alternately-acting lips one above the other, whereby each matrix is engaged by the two lips in succession prior to its delivery by the ejector.

In testimony whereof I hereunto set my hand, this 8th day of March, 1887, in the presence of two attesting witnesses.
